We Tested the 3 Most Popular Ways to Talk Abroad. Only One Passed the Taxi Test.
We Tested the 3 Most Popular Ways to Talk Abroad. Only One Passed the Taxi Test.
Thirty days, three options, five things that matter when you're face to face with someone who doesn't speak English. Every score is published, including the ones that didn't go our way.
Key takeaways
- We scored the free phone app, a screen translator and the ECDF disc on five criteria, 0 to 10.
- Only one option let both people keep their eyes up and answer out loud.
- The ECDF disc scored 47 out of 50 and passed the taxi test; the phone app failed it.
Yes, we make one of the three. So we wrote the rules down before we started, and we are showing every number.
Since July, the message we get most often is a version of "how is your disc different from the app already on my phone?" That is a fair question, and it deserved a fair month.
What we tested, and how
Three ways of talking to someone who doesn't speak your language, the three people mention to us most.
Option A, the big free translation app on a phone. Option B, a screen translator, meaning a handheld gadget with its own display. Option C, the ECDF disc, the round one you wear on a lanyard.
Each one came along for thirty days of ordinary errands: a café, a market, a pharmacy counter, a hotel desk and the back seat of a taxi.
We did not score sound quality or speed, because those are easy to argue about. We scored the five things that change whether a conversation happens at all.
The five criteria, scored 0 to 10
1Speaks out loud, both ways. Can you talk, and can they answer, without anyone reading anything?
2Phone stays in your pocket. Does your phone stay put from start to finish, out of your hand and out of a stranger's?
3Setup. How much fiddling stands between you and the first real sentence?
4Cost over two years. What you pay up front, plus anything that keeps asking for money afterwards.
5How it feels in a real conversation. Do you look like a person talking, or a person operating a device?
Then there is the Taxi Test
Our tie-breaker. You're in the back of a cab, the driver's eyes are on the road, and you need the hotel by the old harbor, not the one by the airport.
He cannot read a screen. You cannot lean over the seat and hold one up to him. Whatever you brought has to speak, and it has to let him speak back.
The scoreboard
| Criterion | Free app | Screen translator | ECDF disc |
|---|---|---|---|
| Speaks out loud, both ways | 5 | 7 | 10 |
| Phone stays in your pocket | 1 | 6 | 10 |
| Setup | 9 | 5 | 8 |
| Cost over two years | 10 | 5 | 9 |
| Feels like a real conversation | 3 | 7 | 10 |
| Total out of 50 | 28 | 30 | 47 |
| Taxi Test | Failed | Half a pass | Passed |
Option A: the big free translation app, 28 out of 50
It costs nothing and it's already on your phone, which is why it takes the setup and cost columns. That is where the good news ends.
Pros: free. Fine for a street sign or a single line on a menu.
Cons: for an actual exchange you type or talk into the phone, then turn the screen toward a stranger, or hand it over. Two people hunched over one phone, tapping between languages, is not a conversation.
Taxi Test: failed. The driver waved the phone away without looking at it, and he was right to.
Option B: the screen translator, 30 out of 50
A dedicated handheld with its own display. Your phone stays in your pocket, which is a real step up, and it does speak.
Pros: one job, one gadget. Better than the phone at a counter, because nobody has to hold your personal device.
Cons: you're still reading a screen and so are they, so both of you look down instead of at each other. It's one more thing to charge and carry, it costs more than free, and depending on the model you may be asked to pay for a plan on top.
Taxi Test: half a pass. We got the hotel name across; getting the answer back meant passing the gadget over the seat.
Option C: the ECDF disc, 47 out of 50
A round disc, matte graphite, hockey-puck size, one microphone button in the center, a small blue light, on a lanyard around your neck or in your palm.
You set it up once in the free ECDF app, choose your two languages, and put the phone away. After that it's one button, and it works wherever your phone works.
Press, talk, and it says your sentence out loud in their language. They answer, press, and it says theirs back to you in English, with no typing, no screen to read and nobody holding your phone.
Pros: the only option where both people keep their eyes up. Hands free, bought once, no subscription and no credits that expire, and it saves every conversation in the app and corrects your grammar when you try the other language yourself.
Cons: it isn't free, and your phone does need to be in your pocket with the app set up. Two points off setup because you do it once at home, one off cost because free is free.
Taxi Test: passed. The driver answered the disc directly, out loud, and never took his eyes off the road.
Why the disc won by that margin
Look back at the five criteria. Three of them are really the same question: does anyone have to look down?
With the app and the screen gadget, someone always does. With the disc, the sentence comes out of the disc and the answer goes back into the disc, and the two of you keep looking at each other.
That is what the taxi driver noticed, and what the woman at the pharmacy counter noticed, and what we stopped noticing after the first week because it started to feel normal.
What to look for
It should talk, in both directions. If the other person has to read, you bought a screen, not a translator.
It should live on your body, not in your hand. Chest or palm, so your phone stays where your wallet is.
One button. If you need to explain the controls to a stranger, the moment has already passed.
Buy once. Ask, before you pay, whether anything renews.
What to avoid
Anything you have to hand over. A stranger holding your unlocked phone is a bigger risk than a wrong order.
Anything that needs both of you looking down. Faces tell you more than the translation does.
Anything that bills you monthly for a trip you take twice a year.

Three questions readers asked during the test
Does the disc need the app? Once, to pair it and pick your two languages. Then it's one button and the phone stays in your pocket.
Both ways, truly? Yes. The same button works for you and for them, which is the whole point of the Taxi Test.
